Stock guylines on backpacking tents, tarps, and hammocks often have two problems. First, the cords are of insufficient length, which limits stake locations. Second, bomber natural anchors like trees and downed logs can't be used.

Skurka's guyline system is simple and much more versatile than stock guylines. It relies on just three easy-to-learn knots, two of which are closely related: the bowline, McCarthy hitch, and the truckers hitch.

The system is secure, fast, and easily adjustable.
